Yanmar 6BY2-260 oil pressure

Postby henningbuus on Wed Jul 10, 2019 10:00 pm

A few months ago I lost all the engine oil while running at high RPM. The Yanmar 6BY2-260 is made by BMW and Yanmar converts it to a marine engine. In that process, an engine oil pressure sensor located below the oil filter and pretty much out of sight is not being used. That sensor had unscrewed itself and the oil pump just ejected all the oil into the bilge. Now I am worried that the engine bearings suffered some damage, so I recorded the oil pressure at various rpms and engine temperatures, and would like to know if this is normal. They are as follows:

Engine rpm engine temperature Oil pressure
1200 116 33
2000
2000

You are missing some numbers. I'm not sure though if even having them will confirm any bearing damage.
